Compound class: Synthetic organic
Comment: Zotiraciclib (TG02) is an orally active multi-kinase inhibitor, with a unique activity profile against CDKs, JAK2 and FLT3 [4-5]. Like pacritinib it is a small molecule macrocycle. TG02 was rationally designed to simultaneously inhibit several key signalling pathways, with the aim of maximising anti-cancer efficacy. It is being investigated for its anti-leukemic potential [2-3].
The compound is administered as the citrate salt.
